Abstract
A configurable circuit breaker, applicable for medium voltage range, with flexibility in configuration, based on the electrical and mechanical constraints. It has multiple poles, which can be fitted on a shaft at required positions, using the clamping, dowelling, bolting etc. An epoxy frame is provided for mounting the circuit breaker on the truck horizontally or vertically, by means of the mounting inserts and the clamping mechanism. The side sheets of the pole allow access to its internal. The flexible contacts and the vertical slots enable adjustability in the incoming and outgoing distances, as per the design constraints. A tulip contact can be connected to the conducting stub in the contactor, for mounting the incoming/outgoing conductor. Common actuator can be mounted anywhere on the shaft, via the movable contact or on any of the poles, which are robust enough. The circuit breaker is hence flexible in size and configuration.
Description
Technical field
The present invention relates to configurable (configurable) circuit breaker, it can be used for different panel (panel) or retrofits at different panels, and has the variable set of design parameters that makes it possible to realize this point.
Background technology
Circuit breaker be used for by its automatically operation come protective circuit can be because of overload impaired switch.Circuit breaker has all size and voltage/current capacity, and selects circuit breaker to use as requested.Key operation is called actuation mechanism, actuation mechanism can be magnetic force, heating power or pyromagnetic power.Actuator is held in place being used for normal running contactor, and makes the contactor motion separately under the situation of overload.Contactor allows electric current to flow when connecting, and when disconnecting interruptive current, thereby protect the influence of the voltage/current of the injury-free property of described circuit level.
Obtainable circuit breaker does not have the flexibility (flexibility) that is suitable for various panel requirements on the market now.In really at the circuit breaker that the remodeling solution is provided for various panels, (VD4 Vmax), and makes it be further adapted for the panel requirement to have used existing circuit breaker.This has introduced the needs to customization connector (epoxy that typically is used for delivered current cast copper and make), and this causes the cost and the design time that increase.Another challenge that presents is that some panels spatially are not oriented the encirclement existing circuit breaker.This circuit breaker that use is pre-existed (its be non-flexibility and for expensive) cause restriction, adapt to different panel requirements thereby cause customizing circuit breaker.These problems have been handled in the configuration of the circuit breaker of the present invention by considering different patterns, installation and encapsulation.Disclosed herein is flexibility configuration circuit breaker, and its whole big I is revised according to the modification of its parts, and these parts can be positioned in the framework of custom configuration of the present invention according to the constraint such as electricity/magnetic isolation and space.
US Patent No 6,462,296 provide the motion (interior and outer) of whole circuit breaker, with electric current frame (current rack) in the layout of in all circuit breakers, using the spitting image of.This invention installation question that is untreated.And the vertical position of member and type thereof are not flexibilities.The quantity of module has the upper limit.The present invention who proposes has overcome these defectives.
The open No 20070159776 of the U.S. discloses a kind of circuit breaker mounting panel that comprises the fork (prong) that is suitable for holding clip.This United States Patent (USP) has proposed to be used to install the solution of circuit breaker.This invention configuration of being untreated, configuration is a target of the present invention.
US Patent No 5,566,818 relate to the movable contactor device in a kind of circuit breaker (for example wiring circuit breaker and earth leakage circuit breaker).In this United States Patent (USP), arrange in such a manner by two circuit breaker elements that strap is formed, that is, make contactor elements parallel to each other and independently of one another, to be formed for the movable contactor of each phase.This invention is untreated as configuration, encapsulation or installation question among the present invention who proposes.This invents the contactor that only consideration makes conductor be connected with circuit breaker.
US Patent No 6,337,613 disclose a kind of three-phase that has or do not have neutral point (neutral), high current switching appliance arrangement, and it comprises the utmost point compartment that is connected in parallel.This invention has proposed that electric current between 3 phase switchgear device and circuit breaker bipolar distributes and the optimization or the improvement of temperature.This invention does not consider that variable configuration or installation, variable structure or installation are targets of the present invention.
File EP1775744 discloses the method for a kind of preprocessing (Preparation) three-pole breaker.Three utmost point power switchs have switch lock, and wherein, the quick short circuit that respectively has itself is triped so that trip spindle is worked.Flexibility configuration and remodeling are not considered in this invention, and flexibility configuration and remodeling are targets of the present invention.
US Patent No 7,187,258 disclose a kind of circuit breaker such as molded shell circuit breaker or earth leakage circuit breaker, and it has the movable contact that is disconnected by electromagnetic repulsive force when big electric current (for example short circuit current) flows.This patent is operated about using electromagnetic force, and considers the flexibility configuration or the installation question that are associated with circuit breaker.And this patent remodeling that is untreated.This invention relates in particular to the circuit breaker with over cap of being made by insulating material, and this over cap covers movable contact, to eliminate the contact electric arc that produces when contact disconnects.
US Patent No 4,950,854 do not consider design, the configuration flexibility of circuit breaker, the design of circuit breaker, configuration flexibility are targets of the present invention.The circuit breaker that this invention only discloses with vacuumizing replaces old-fashioned ambient magnetic circuit breaker, and does not have modification in compartment (cubicle).
United States Patent (USP) 3,973,096 pair of main contact provides less adjustability, but only for changing type switching device unit over to, and the present invention to be circuit breaker (not considering type) provide this solution.Installation, encapsulation and design problem are not considered in this invention yet.
Manage to adapt to the existing circuit breaker of the panel that varies in size and accomplish these by end coupling being modified as suitable panel.This has proposed various restrictions, for example space constraint, can't be fit to have the panel of different sleeve design, movable or to be fixed on a position medium.The present invention proposes the flexibility design, handled the restriction of prior art.
Summary of the invention
Target of the present invention provides a kind of flexibility circuit breaker, and it can easily be retrofitted in the existing panel or be used for new panel.The solution of prior art have fixing pole span from, need be used for the path member of panel.This has also introduced the constraint to space requirement.Another target of the present invention provides a kind of independently circuit breaker of the utmost point that has or do not have, and can be configured this circuit breaker.Configurable circuit breaker of the present invention has variable distance between its utmost point, so that adapt to various panel sizes.Circuit breaker of the present invention also has movable input arm and output arm, and input arm and output arm are movable, to adapt to the various panel sleeve design on the different panels.In addition, circuit breaker of the present invention can be used in level or the vertical configuration.
